What problem does it solve?
Cryptography challenges in offline environments are time-consuming; this toolkit provides modular attack scripts for RSA, classic ciphers, and XOR analysis to accelerate solution workflows.
Core Features & Use Cases
- RSA attacks: small exponent, Wiener, common modulus, Fermat factorization, and key-recovery helpers.
- Classical ciphers: Caesar, Vigenere, and XOR analysis with frequency scoring.
- Frequency analysis and offline tooling for rapid hypothesis testing on intercepted texts.
Quick Start
Run a sample RSA or cipher challenge to see how the tools recover plaintext.
